Table G. Common Faults
Fault Codes
Failure Code Failure Description
E1 High pressure protection
E2 Low pressure protection
E3 Low water pressure protection
E4
Single phase unit: loose wire terminal at
PROT2 on the PC board
Three phase unit: 3 phase sequence
protection
P1 Pool water temp sensor failure
